FILTER.

SPECIFICATION forming part of Letters Patent N 0. 561,673, dated June 9,1896.

Application filed December 10, 1895. Serial No. 571,685. (No model.)

' To all whom it 77mg; concern:

Be it known that 1, CHARLES A. KL' NZEL, Jr., a citizen of the UnitedStates, residing at I-lobolcen, in the county of Hudson, State of NewJersey, have invented a new and useful Improvement in Filters, whichimprovement is fully set forth in the following specification andaccompanying drawing.

My invention consists of an improvement in filters, whereby the fluid issubjected to a double filtration.

It also consists of a novel method of constructing the filter, wherebyit may be easily cleansed.

The figure represents a vertical section of a filter embodying myinvention.

Referring to the drawing, A designates the casing of a filter, havingthe compartments B, O, and D, the same being bolted or otherwise securedto each other. On the inner walls of the compartment B are the flanges Eand F. The former supports the perforated diaphragm G, the samecompletely covering the opening and having on top the netting II, onwhich is charcoal or other filtering material. 011 the flange F is adiaphragm having at the center the convex projection K,

forming a deflector, and the perforated rim K,

on which latter is netting H, supported by the flange F, and inclosingthe rim K is the conical vessel J, on the top of which are fitted thetelescopic pipes L and M. On the inner wall of the casing, and betweenthe compartments 0 and D, is a flange P, on which is sustained thediaphragm N, which is covered by netting Q. Support-ed on said diaphragmN, directly over the pipe M, is the pipe R, the wall of which isperforated and covered by netting U", said pipe being supplied with anysuitable filtering material, as at S. A cup T is placed around thebottom of the pipe R, closely fitting the same, and netting U secured tothe upper edge of said cup and to the diaphragm N at a point over theflange P, said cup and netting being conical in reverse order.

V designates the outlet-pipe, which is connected with the wall of thecompartment 0. The top of the casing is closed by a cap V, which is heldin place by the screw X and bridge Y, said cap being adapted to beloosened and removed, whereby the filter may be through the strainer Uand the portion of the diaphragm N below the same into the compartment0-, from which it is withdrawn through the discharge or outlet V. Itwill be seen that the fluid is thus subjected to several filteringactions, while the device is of an inexpensive construction.

Between the opening of the casing and the pipe R is a chamber A, havinga pipe 13 leading thereto, through which water may be introduced toclean the filter, part of said water passing down the pipes B M L andthe vessel J and through the various diaphragms and out at Z, whileanother part passes through the side of the pipe R, the strainer U, andthe diaphragm l into the chambers G and D, and passes out at thedischargepipe V.

The various parts of the filter may be separated and removed for purposeof repairs, &c.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A filter having a casing with an inlet, upper and lower perforateddiaphragms connected with said casing, forming a filteringchamber,theupper one of said diaphragms having a perforated rim with animperforated convex portion projecting into said chamber, forming adeflector, a vessel within said casing, receiving the fluid from saidfilteringohamber, an upper filtering-chamber communicating with saidfiltering-chamber, and a discharge-pipe in communication with said upperfiltering-chamber, said parts bein g combined substantially asdescribed.

2. A filter having a casing with an inlet a vessel J with the pipes L,M, thereon open to said inlet, diaphragms above and below said pipes andvessel, and a perforated pipe supported on the upper diaphragm, saidperforated pipe having communication with the IOO space in the casingoutside of and adjacent to said vessel J substantially as described.

3. A filter having a casing with inlet upper and lower diaphragms, thevessel J with pipes L, M, between said diaphragms, the perforated pipeabove said diaphragms, the cup T surrounding the pipe R, and thestrainer U, connected with the cup '1 and the upper diaphragm, saidparts being combined, substantially as described.

4. A filter formed of compartments with diaphragms between the same,inlet and outlet pipes, the vessel J above the intermediate diaphragmwith the communicating pipes L, M, a perforated pipe above the upperdiaphragm which is in communication with said conveying-pipes and withthe compartment surrounding the same, and a deflector with a perforatedrim below said vessel, said parts being combined substantially asdescribed.

5. A filter consisting of sections having flanges on their inner Walls,diaphragms form ing a filtering-chamber connected with the flanges onthe lower section above an inlet thereon, a conical vessel on the upperone of said diaphragms, a perforated diaphragm above said conicalvessel, a perforated pipe on said perforated diaphragm, andcommunicating with said vessel, a cup surrounding said perforated pipe,a strainer secured to said cup and perforated diaphragm, and adischarge-port in the casing of the filter adjacent to the base of thesaid conical vessel, said parts being combined substantially asdescribed.
